GRAND HAVEN -- After last week's killing of a jewelry store owner and a customer, police found a fingerprint of Darick O'Brien Anderson near a safe in an area off-limits to visitors of the downtown business, a detective told a judge.

Police, in retracing Anderson's moves after the slayings, found that Anderson -- a convicted robber -- spent at least $2,200 the day after the slaying and flashed thousands more. Police found cash and jewelry during searches of several places in the Muskegon area where Anderson lived.

Grand Haven police Detective Tim Bulthuis, in obtaining warrants against Anderson, described evidence that a task force of area police officers gathered after the Wednesday afternoon slayings of Robert Karell, 61, owner of R.K. Jewelers, and Louis Paparella, 76, who were found inside the store at 124 Washington St.

The store owner's daughter, Stacey, found the victims around 3:30 p.m. Wednesday. Both had been shot in the head.

Bulthuis said that police also found ammunition consistent with that used in the shootings.

Anderson, 42, was ordered held without bond and charged with two counts of open murder, armed robbery and being a fourth-offense habitual offender. At his arraignment before Grand Haven District Judge Richard Kloote, he appeared annoyed at times, even turning his head without answering when asked if he had any questions about the proceedings.

Before the arraignment, Bulthuis outlined evidence against Anderson, who was born in Chicago, but spent most of his life in the Muskegon area.

Once police determined that Anderson was a suspect, they looked into his whereabouts after the slayings. Police determined that the next day, he spent $2,200 in $100 bills at an undisclosed business, and later flashed $10,000 at a car dealership where he tried to buy a vehicle.

"The employees stated that there were numerous $100 bills that would've been taken from the safe," Bulthuis told the judge.

Police still were taking inventory at the store to determine exactly what had been taken.

Anderson was arrested late Saturday night and booked into the Ottawa County Jail early Sunday.

"I think we can assume all this stems from a robbery," Dennis Edwards, director of public safety, said Monday.

The task force was comprised of more than 20 investigators from his department, state police, sheriffs' departments in Muskegon and Ottawa counties, police departments in Muskegon and Muskegon Heights and the state Department of Corrections.

Edwards said it was important to the victims' families, the business district and the community to "know that Grand Haven is a safe place."

Karell founded the store nearly 30 years ago, and he was a fixture in the Grand Haven downtown business district. One of Louis and Rose Paparella's five children, David Paparella, said his family was focused on the investigation and referred calls to police.

Anderson was convicted of four 1991 armed-robbery charges, which led to a prison sentence of 10 to 30 years, along with a two-year consecutive term for felony firearms, state police records showed. Department of Corrections records showed that Anderson was released April 25, 2007.

His release was designated an "early discharge," but prisons spokesman Russ Marlan said Anderson, eligible for parole in March 2003, served longer than the minimum term. Truth-in-sentencing laws, which took effect in 1998 and require at least the minimum sentence be served, were not in effect when Anderson was sentenced in 1992.

The Parole Board rejected Anderson's previous attempts at parole before he was released in March 2005, with another two years to be served on parole. He received the "early discharge" designation because he still owed about $400 in costs when discharged.

Like other prisoners sentenced before the 1998 law went into effect, Anderson could have his sentence reduced for good time and other credits.

Six months after being released from prison where he served years for multiple armed robberies, Anderson was charged in 2007 with assaulting a Muskegon man with a shotgun and butcher knife. Those charges were later dismissed pending further investigation.

Back in 1992, Anderson was sentenced to prison on four armed robbery charges and a felony firearm charge. The robberies were "clearly linked to the use of crack cocaine," Muskegon County Prosecutor Tony Tague said in 1991.

Anderson and an accomplice, Terrence Lee Rogers of Muskegon Heights, were arrested less than a half-hour after an armed robbery at Pletcher's Furniture, 2152 S. Getty.

Anderson later pleaded guilty to four armed robberies -- one credit union and three gas stations -- and a felony firearm count.

As part of a plea agreement, Anderson testified against Rogers in the furniture store robbery and against others charged in additional robberies. At the time, a task force of investigators from several area police agencies had been working to solve a string of 40 armed robberies that began in September.

Anderson's record also shows a 1986 conviction for prison escape, which was from a transitional corrections center in Muskegon.
